I seldom indulge, but I share Ben Franklin thoughts:
"Those who would give up Essential Liberty to purchase a little Temporary Safety, deserve neither Liberty nor Safety."
What has the MADD franchise pursuaded you so easily to give up, so that they may continue to line their pockets with $$$$$$$, at the cost of your freedoms. Don't be so gullible; there are reasonable risks that reasonable people can easily chose to avoid. For one thing, if you are really concerned, you may avoid driving around during the peak hours when bars close in your area. Don't allow someone's ghost story to stampede you into surrendering the freedom to chose. You don't need a sobriety check point if you don't drink, you already know you are sober. The stuff costs money, impedes traffic flow, and harrasses the innocent.
It may be law; a bad law, a law which should be changed.
